1求可⽤被17整除的所有三位数

fornuminrange(99,1000):

ifnum%17==0:

printnum

ps:下⾯的写法和上⾯的写法性能的差距,上⾯好吧?

fornuminrange(99,1000):

ifnum%17==0:

printnum

else:

continue

2连续整数之合

>>>sum=0

>>>x=int(raw_input('plsinputx:'))

plsinputx:22

>>>fornuminrange(0,x):

...sum+=num

...

>>>printsum

231

>>>

累加

x=int(raw_input('pleaseinputx:'))

layer=1

whilelayer<=x:

lsum=0

count=1
whilecount<=layer:

lsum+=count

count+=1

fstr=''

fornuminrange(1,layer):

fstr=fstr+str(num)+'+'

fstr+=str(layer)

printfstr,'=',lsum

layer+=1

==============

pleaseinputx:5

1=1

1+2=3

1+2+3=6

1+2+3+4=10

1+2+3+4+5=15

#如何控制空格的数量让等号在⼀起呢

整数和能整除数字个数,奇数

x=int(raw_input('pleaseinputx:'))

fornuminrange(1,x):

#printnum

sum=0

foryinrange(1,num+1):

sum+=y

ifsum%num==0:

printnum,'---',sum
